Answer:

595.

Step-by-step explanation:

Take $2000 and subtract $810 from it. You now have the total of the two pieces of equipment without the extra pricing. You should get $1,190. Then divide that number by 2. You will get $595.

1st Piece of Equipment = $595

2nd Piece of Equipment = $1,405

2nd Piece is $810 more expensive and the two pieces combined is $2,000.

The correct answer for the intercept c'(100) is 0.04.

According to the question, the given expression for the cost function in terms of intercept is as written below:

[tex]c(q)=84+0.16q-0.0006q^{2} +0.00000q^{3}[/tex]

Differentiate the given expression and it can be re-written as:

[tex]c'(q)=0+0.16-0.0006(2q) +0.00000(3q^{2})[/tex]

Now, substituting the value of the variable 'q' as 100:

[tex]c'(100)=0+0.16-0.0006(2(100)) +0.00000(3(100)^{2})\\ c'(100)=0.16-0.0006(200) +0.00000(30000)[/tex]

⇒c'(100) = 0.16 - 0.12 =

  c'(100) = 0.04

Hence, the correct answer for the intercept c'(100) is 0.04.

Answer:

5.7

Step-by-step explanation:

5.666666666 can be rounded to 5.7 because the first decimal place occurs immediately after the decimal point.

I.e. in the number 1.23456, the first decimal place value is 2.

Meaning when we round, we look at the second decimal place. Given that 5.666666666 has a second decimal place greater that 5, we can round to 5.7

The area of the base of a prism with a square base is 7,200,000/h cm to the 2nd power.

The formula for volume of square prism is given as,

Volume of a square prism = (Base Area) × Height.

Now it is given that,

Volume of prism = 7,200,000 cm to the 3rd power

Height of prism = h cm

Since, Volume of a square prism = (Base Area) × Height

Putting the values we get,

7,200,000 = (Base Area) × h

Rearranging we get,

Base Area = 7,200,000 / h cm to the 2nd power

Thus, the area of the base of a prism with a square base is 7,200,000/h cm to the 2nd power.

By applying the supplementary angle theorem, the magnitude of angle B (m<B) is equal to 38°.

A supplementary angle can be defined as two (2) angles or arc whose sum is equal to 180 degrees.

Mathematically, a supplementary angle can be calculated by using this formula:

Q + R = 180

Where:

Q and R are measure of the angles subtended.

m<ADC = 180° - 110°

m<ADC = 70°

Substituting the given parameters into the formula, we have;

m<ADC + m<DAC + m<ACB = 180

70 + 46 + m<ACB = 180

116 + m<ACB = 180

m<ACB = 180 - 116

m<ACB = 64°

Now, we can determine the magnitude of angle B (m<B) based on the given diagram:

m<B = 180 - (m<CAB + m<ACB)

m<B = 180 - (78 + 64)

m<B = 180 - 142

m<B = 38°
